drm/atomic: Pass the full state to CRTC atomic_check

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's start convert all the remaining helpers to provide a consistent
interface, starting with the CRTC's atomic_check.

The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.
